I don't know how in the holy mother of fudge this got a million views, but I feel totally honoured! Thanks everyone :D
This is a 100% longplay -- all level exits and Dragon Coins are shown. This was recorded on the snes9x emulator. I did die more than a few times (I'm not a miracle worker!) -- I edited out the deaths afterwards, so none of them appear in the video. I also did a bit of editing towards the end of the video, in the final level. Normally the player just picks two rooms and can't access the other six, but for completion's sake I decided to show all of them.
Lastly, you might notice that I crouch a lot, seemingly at random. That's just my USB controller being weird.
Shoutout to my friend Aidan for inspiring me to make this video. He has tons of terrific longplays on his channel, check it out:
